STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I am using STM32L072xx module and I would like to use ADC4, ADC5 and ADC 17 (Vrefint) at the same time. But I want to use ADC4 with DMA of buffer size 500 or more. It is not necessary to store ADC5 & ADC17 in DMA.Can I use DMA only for ADC 4 and dump...
Hello!Please advise on the proper way to change IP and MAC address during runtime.Are there any standard ways of doing this? Are there any reinitilizations needed? which functions to use? thanks in advance!
I am making a ntc thermometer with stm32f103c8 (by writing over registers without using state library). The code works as it is,I did the adc conversion in 7.5 cycles. I used the calibration register and ran the adc in continuous conversion mode. but...
Is there example code for EEPROM Emulation of the H7 series? I can only find it for older STM32 devices and it states that other devices should use different code.If not can anyone confirm the smallest sector of the internal Flash that can be used? I...
Hi All,This is not really a specific STM32 question I suppose, so please excuse what might seem like a simple maths question for some of you. How can I do a 1/x operation to a FLT number without using the VDIV command?VDIV takes 14 clock cycles to ...
Hi!I'm doing SDADC and I think there is some issues with the DMA for SDADC in STM32CubeIDE 1.7.0.First, I have enabled DMA for SDADC1, SDADC2, SDADC3 and I have selected InjectedConversion = ENABLE. Then I run this function. volatile static int16_t S...
Have a device built around an 32f429 which appears to be hard faulting too infrequently to catch on the bench with debugger attached -- but have lab personnel running all day and getting the errors, not infrequently enough.I can use some BKUP registe...
I have a problem transmitting a byte with SPI using DMA and asking for your help to solve this issue.Used uC: STM32F405RGT6Target: Display ST7789Project generated with STM32CubeIDEToolchain/IDE: Keil uVisionSPI 2 used/configured as "transmit only, ma...
Hello,I am new to ST development ecosystem. I want to use the sample applications(specific to a dev kit) provided as part of the cube expansion packages for our custom board. Any help on the steps or a reference to a document on tweaking existing app...
Hello, I have a power converter device controlled by a STM32L475RC. One part of the control requires a constant PWM of 70kHz of 300ns (Ton). Although this pwm is never modified,and doesn't use interrupts or DMA modules, periodically it produces a gl...
